The Forestry Department is using a <u>chemical</u> control method. This involves using a <u>foliar spray </u>method, in which department personnel will spray pesticide directly on the trees’ leaves.
Explanation:
The chemical control method of pesticide control involves spraying chemical pesticides directly on leaves, shoots or roots of the plants. These chemicals are toxic to the pests only and the pests get retracted from the plants because of the pesticides applied.
A selective pesticide application is done to limit application to a target harmful pest which kills only that and does not harm the other useful or harmless species which thrives on the plants.
White pine blister causes rust of the branches and leaves of the pine trees. Hence, a foliar spray of the pesticide is done to control its spread.
Foliated rock: a rock that has distinct and repetitive layers. Layers are formed because each layer endures different levels of heat and pressure.
Non-foliated rock: a rock that does not have any visible layers, formed under high temperatures.
